Could you imagine Salt Lake City without cars?

Maybe not COMPLETELY without cars, but without having to use cars to get around for all the daily needs. I don't like cars. I don't hate cars — they're very useful for what they show in the commercials; driving up super-windy roads to go skiing, or camping in the great outdoors, but besides that I don't want to use one a regular basis.

I'd rather to get to work and go to the store this way ...

Or this way ...Not this way ...

It should be a civil right to be able to satisfy most daily needs without having to rely on a car. They're expensive and there should be convenient, efficient alternatives for everyone.

Back to the question — I could imagine a Salt Lake City without cars; it's a long shot, but I could, at least the urban core. With all of the existing planned and proposed mass transit and bike lanes, it could be done.

What changes/sacrifices would I have to make a car-free Salt Lake City more realistic?
